Title: Measuring physical value using parallel electrical model - reducing measurement delay using auxiliary sensor and differential circuit
Inventor: GAST THEODOR PROF DR ING
IPC: G01K1/20
Filed: 1980-06-27
Abstract: The measuring arrangement, using an electrical transducer and an electrical parallel model with feedback, contains a logic element and amplifier and is aimed at measurement with minimal delay. Delays due to temp. variations are eliminated and costs reduced. A measurement arrangement placed near the physical parameter sensor produces an auxiliary electrical signal which is differentiated with the sensor signal. The output of the difference circuit is combined with the output of the parallel model and fed to the amplifier. The parallel model time response is adjusted for the effect on the measurement system of the difference circuit. The arrangement may be used for temp. measurement of conveyed goods, e.g. tobacco.

Title: Dust filter for air - comprises filter bags suspended by internal pipe length from perforated plate with easily released clamp
Inventor: WUKOJEWITSCH HANS
IPC: B01D46/00
Filed: 1980-07-22
Abstract: A series of filter bags (2) are suspended from a perforated plate (6) forming a barrier between the clean side (above) and dirty side (below). The top of each filter bag (2) is fitted onto a short length of pipe (9), which has a flange (20) around its top edge, this flange resting on the perforated plate (6). The mouth of the bag is trapped between this flange and the perforated plate, the clamping force being provided by a clamping element (23,24) bearing against the opposite side of the perforated plate (6); at the bottom each filter bag (2) is tensioned by a tensioning device to a frame or a component (31) connected to the filter frame. For air filters where the dirty side is outside the filter bag, and for periodic cleaning, air jets are blown into the inside of the bag to cause the dust to fall off. The arrangement is compact, allows the bags to be thoroughly tensioned between their upper and lower ends, and enables bags to be easily cleaned by simple unscrewing the clamping device.

Title: Insertion of documents into printing terminal - uses photodetectors to start and control rollers to ensure correct levelling after document is lowered into hopper
Inventor: VIDAL JORGE
IPC: B41J11/55
Filed: 1980-08-25
Abstract: Photoelectric sensors detect the presence of the lower edge of a document inserted into an alphanumeric printing terminal of a data processing system. These sensors control the rollers to ensure the document is correctly levelled. A document (3) is lowered into a hopper (1) which terminates in a rigid sheet (2) to form a backplate for the printing action. A photoelectric sensor (5) detects the passage of the lower edge of the document and provides a signal for a programmer (25). The programmer starts the drive mechanism motors (14,15) to rotate the rollers (6,7). Two sensors (23,24) detect the presence of the lower edge of the document and consequently stop the relevant motor until both detectors signal presence of the document. From that moment the motors operate in synchronism to displace the document.

Title: Sewage aeration system - creates vortex by free fall in thin curtains
Inventor: UEBERALL PETER
IPC: B01F3/04
Filed: 1980-09-19
Abstract: A system for the aeration of sewage and sludge, esp. in sewage treatment, based on activated sludge sedimentation, creates a curtain by allowing a thin stream of the liq. to descend in a free fall into a basin where it creates a vortex with a strong stirring action. The height of fall is kept constant by circulating at least a part of the liq. which has become aerated by the vortex action. This creates a simple process of high functional reliability which is unaffected by froth and floating sludge. Its capital and operating costs are low and it requires little space.

Title: System for separating solids from liquid - with rotating screen collecting solids subsequently entrained in gas stream
Inventor: DUCASSE JOSEPH CHRISTOPHE VICT
IPC: B01D33/00
Filed: 1980-09-24
Abstract: Liq. and solids are sepd. using an appts. which includes a stationary casing divided into upper and lower chambers by a horizontal rotating screen. The lower chamber has a first outlet for liq., and a second outlet above the first for evacuation of the lower chamber. A fixed scraper is positioned above the screen. An inlet conduit adjacent the scraper deposits a slurry on the screen to form a layer on the rotating screen. A gas stream is directed across the path of the solids as they encounter the scraper. This entrains the solids, completes their drying and directs them to an outlet. Gas is directed into the upper chamber to pass through the slurry layer when the lower chamber is evacuated. This displaces the liq. through the screen and dries the solids. The appts. is partic. described for sepg. sugar crystals from molasses in massecuite. Crystal breakage is minimised.

Title: Chocolate paste spraying plant - operates two alternate spray nozzles with sharp-ended ellipses as apertures
Inventor: HUEBNER ECKHARD
IPC: A23G1/18
Filed: 1980-11-27
Abstract: A plant for the high-pressure spraying of chocolate paste, e.g. on moulds in the automated production of hollow chocolate articles for filling, uses a valve to spray the paste through a vibratory screen on a storage vessel which is designed as a weighing container. A high-pressure pump extracts the paste and passes it through a flexible hose to two spray nozzles. A programmer actuates each nozzle inturn for an equal time interval. The nozzles have apertures with the section of a sharp- ended ellipse. Intervals of rest allow any solid particles in the nozzles to re- orient themselves and to be cleared out at the next turn. The degree of clogging can be easily controlled and stoppages prevented.

Title: Method and arrangement for operating a travel governor in electric power units or locomotives
Inventor: GAST JENS-PETER DIPL ING
IPC: B60L15/20
Filed: 1981-02-19
Abstract: The invention relates to a method for operating a travel governor in electric power units or locomotives using micro-computer hardware which carries out the vehicle control or governing. In order to lower the relatively large amount of computing time required for administration and to reduce the memory requirement, it is proposed according to the invention:   - to preselect the control signals according to operating states or functional similarity (e.g. travelling, braking, switching unit acknowledgement) and combine in corresponding signal groups (e.g. n) in which in each case the significant phases of the operating states are detected, - each signalling group (e.g. n) is assigned an interrupt prestage (e.g. 19.n) which compares signal value changes within the group, data words (e.g. in 8-bit code) being allocated to the significant phases, - when signal value differences are detected, an interrupt command is issued by the respective interrupt prestage (e.g. 19.n), which command causes the computer (1,2,3) to immediately process only the respective significant operating state phase. A further advantage is that only one microprocessor is required.   <IMAGE>

Title: Arrangement and method for section-by-section measurement of permanently connected transmission paths in telecommunications systems
Inventor: VIERLING OSKAR
IPC: H04M3/32
Filed: 1981-03-19
Abstract: Arrangement and method for section-by-section measurement of permanently connected transmission paths in telecommunications systems. The problem of measuring dedicated lines on a section-by-section basis from a central location (A) is solved. The dedicated lines (F and F' in Fig. 2) are disconnected in each exchange (A, B and C) on the intermediate distributor and routed via line couplers (LKA, LKB, LKC) which can be adjusted by remote control and which allow the transmission path to be disconnected and measuring devices to be connected on either side of the disconnection point. The measuring devices and their connection and control devices are combined in the measuring arrangements (MA, MB and MC). B and C are unmanned distant stations. Their line couplers (LKB and LKC) are adjusted and the measuring devices which are required in each case are activated and controlled from A via a connection L or L' of the existing STD service (DDD) test network. The return transmission of the test results arising in B or C is also carried out via this connection, along with the signal transmission. If firstly the connection L and then the connection L' are set up as shown in Fig. 2a, firstly section A-B and then section A-C can be monitored. With two parallel STD service (DDD) connections L and L' as shown in Fig. 2b, section B-C can be monitored independently. The measuring point A does not therefore need to be the starting point of the dedicated line under test. <IMAGE>

Title: Pressure-resistant insulation arrangement for heated presses
Inventor: BODE MICHAEL ING GRAD
IPC: B29C45/73
Filed: 1981-09-04
Abstract: For the pressure-resistant thermal insulation between a press plate and a heated mould attached thereto, a pressure-transmitting element is used which, for pressure transmission, contains ceramic bodies which may be formed as a more or less uniform layer or from a multiplicity of separate individual bodies. Apart from the comparatively low thermal conductivity coefficient and the thickness of the ceramic material, the thermal insulation results from the reduction of the cross-section available for heat transmission.
